Troubleshooting QUESTION What should I do to get the strongest Wi-Fi signal? How can I connect the washer or dryer with a smartphone stably? What should I have to do when the number of the antenna bars that are displayed on the LCD of the washer or dryer is 1? ANSWER • Install the AP near the washer or dryer is recommended. You can check the signal strength through the setup screen of the washer or dryer or a smartphone. • Since network performance is seriously affected by a door or steel wall, install the washer or dryer in an open place. If there is door in front of the installed product, open the door when using the product. • Do not place an object made with steel or glass in front of the front LCD of the washer since it blocks the radio signal. • Note that the radio signal may be weakened or interfered with and the communication with the smartphone may fail when a microwave oven is used in the house. • Install the washer or dryer so that the front of the product faces the AP if available. • When the signal strenth that is displayed on the LCD of the washer or dryer is weak, the control may fail. For stable operation, the measures of signal strength should be as follows: • At least 3 antenna bars should be displayed on the LCD of the washer or dryer. • At least 3 antenna bars for the Wi-Fi connection should be displayed on the smartphone. • When the signal strenth is measured with a smartphone app that shows the Wi-Fi signal strength, the signal strength should be stronger than -65 dBm. (E.g. -60 dBm and -50 dBm are stronger than -65 dBm.) • When the signal strenth that is displayed on the LCD of the washer or dryer is weak, the control may fail. In this case, take the following measures for normal operation. • Move the AP closer to the washer or dryer. (At least 3 antenna bars should be dislayed in the network setup of the washer for proper operation.) • Because an old AP may provide lower performance, use a new AP if available. • Position the antenna of the AP so that the radio signal is more easily propagated. 70_ Troubleshooting DV455-02836F-02_EN_20120625.indd Sec6:70 2012-06-25 5:21:25

QUESTION
ANSWER
What should I do to get the
strongest Wi-Fi signal?
•
Install the AP near the washer or dryer is recommended. You can
check the signal strength through the setup screen of the washer or
dryer or a smartphone.
•
Since network performance is seriously affected by a door or steel
wall, install the washer or dryer in an open place. If there is door in
front of the installed product, open the door when using the product.
•
Do not place an object made with steel or glass in front of the front
LCD of the washer since it blocks the radio signal.
•
Note that the radio signal may be weakened or interfered with and
the communication with the smartphone may fail when a microwave
oven is used in the house.
•
Install the washer or dryer so that the front of the product faces the
AP if available.
How can I connect the
washer or dryer with a
smartphone stably?
•
When the signal strenth that is displayed on the LCD of the washer or
dryer is weak, the control may fail. For stable operation, the measures
of signal strength should be as follows:
•
At least 3 antenna bars should be displayed on the LCD of the
washer or dryer.
•
At least 3 antenna bars for the Wi-Fi connection should be
displayed on the smartphone.
•
When the signal strenth is measured with a smartphone app that
shows the Wi-Fi signal strength, the signal strength should be
stronger than -65 dBm. (E.g. -60 dBm and -50 dBm are stronger
than -65 dBm.)
What should I have to
do when the number of
the antenna bars that are
displayed on the LCD of the
washer or dryer is 1?
•
When the signal strenth that is displayed on the LCD of the washer
or dryer is weak, the control may fail. In this case, take the following
measures for normal operation.
•
Move the AP closer to the washer or dryer.
(At least 3 antenna bars should be dislayed in the network setup
of the washer for proper operation.)
•
Because an old AP may provide lower performance, use a new
AP if available.
•
Position the antenna of the AP so that the radio signal is more
easily propagated.
